Bike hacking at the Red Bull Basement

On August 23rd, Paloma Oliveira and I coordinated a workshop for the crafting of do-it-yourself bicycle lights, during the Red Bull Basement, a great cultural event curated by Gisela Domschke and hosted by Red Bull Station. These bike lights are made of recycled materials and simple electronic components, and allow the hacker/biker to become more visible at night. Nevertheless, the workshop served as an introduction to electronics for most participants, who for for first time realised electronic devices can be handcrafted and personally designed.

If you are interested in building your own bike light, you can download the manual we have created with instructions and illustrations. Have fun and share your results!

Below are some pictures taken during the workshop. For further information about the event, check out the official website.

Design applied to multimedia installations

design aplicado a instalações multimídia com projeção

From the 13th to the 15th of March, i’ll be at the Trackers Cultural Center, in São Paulo, Brazil, to give a short workshop which purpose is to provide an intense and productive space for the study and production of multimedia installations that include the use of projection techniques. This workshop is based on previous ones I have given on the subject, but this time we’ll be focusing on design thinking and models applied to projects that address the use of projected images.

We’ll be using three main tools in order to experiment with this sort of media: VPT – a well known open source projection mapping tool developed by HC Gilje -, LPMT – also an open source projection mapping tool, a very nice option for Linux users – and Google Sketchup, in order to sketch and analyse possible projection situations.

Projection mapping has become a well known and creative use of visual language applied to unusual contexts. the technology calls the attention of a wide variety of professionals, enthusiasts and researchers, with different knowledge backgrounds. hence, a proper design model is important, considering the diversity of disciplines and techniques such projects usually require. It is interesting to understand how a projector works, what are its components, how does the image “fit” the projection support, how should a video be formatted in order to suit specific projection surfaces, how can a projection mapping situation be properly calculated, and so forth.

Therefore, the program of the workshop is proposed as the following:

Day 1 (13/03): introduction to design thinking applied to projection technology

What sorts of knowledge are related to projection mapping technology? What is a projector, and how it works? What sorts of equipment should be considered in such projects? What about video formatting? These common questions will be addressed while we introduce a methodology that can be used in several kinds of projection situations. We’ll do a little exercise in which the participants will be invited to create an installation and sketch it on Google Sketchup.

Day 2 (14/03): VPT and LPMT  – adapting images using software

This is the day in which i’ll introduce the two projection mapping tools, and explain a little bit about certain coherences and differences between virtual and “real” world texturing. We’ll be going through typical mapping techniques, such as vertex distortion, masking and frame blending. as an exercise, the participants will be invited to adapt images and videos of their choice to the support they have chosen in the previous day.

Day 3 (15/03): wrapping all up

In the last day, participants will be able to finish their installations and have time for specific questions that eventually could not be answered during the previous days.

Hope to see you there!

Fatto in Casa // Panoramica 2012

fatto in casa - panoramica 2012

And 2012 starts with another presentation of Fatto in Casa, with one of my mentors, Jorge Crowe. We’ll be performing in the Panoramica Festival, at the Espacio Fundación Telefonica, in Buenos Aires (1540 Arenales St.), on Saturday, March 10th, at 7pm. Expect a few improvements on the visuals this time: audiovisual sync via Arduino + PDuino, toys that get lit when in use over the jugetomatica (the interface i use for the realtime visual remix), and a few things more 😉

Please visit the official website of the event for more info:

Hope to see you there!

Modified toys occupy Buenos Aires

fatto in casa jorge crowe

If you are not aware of the modified toys that are occupying Buenos Aires (ok, just an opportunist joke), you will now have four chances to meet them. Jorge Crowe and I will be presenting the live audiovisual performance Fatto in Casa in several opportunities in the next few days at the capital of the Porteños.

For those who don’t know the perfomance, Fatto in Casa explores the re-use and modification of old toys and objects as an audiovisual platform. Jorge plays the soundscapes with a huge set of little frankensteins, while i modify video images taken from his set in real time, using a very improvised prototype based on the Reactable project. We’ve already presented the performance two times earlier this year, and we invite you to check out the next toy attacks!

The first jam will be held on Saturday, December 10th, at the Street a delika, in the Zafra espacio de formación artística (3096 Sarmiento St.), at 5pm.

street a delika

On the 11th, we will be performing at the E.A.S.T. – Encuentro de arte sonoro en transito, in the Galería Patio del Liceo (2729 Santa Fé Av.), from 4pm on.

encuentro de arte sonoro en transito

Then, on Thursday, December 15th, we will be at the Espacio Ecléctico, in a very nice event called Genealogía del Objeto. our noise starts at 8pm.

Thinking the urbe: AVLab Córdoba September 2011

The 4th instalment of the AVLab Córdoba meetings (remember the last one?), curated by daniel gonzález xavier, will take place at the local centro cultural españa, on the  19th and 20th of september. this time, the event proposes a discussion around a theme that is brought back every once in a while, underlining an insistent necessity to rethink the urban and informational scapes. It is clear now that the urbe can be analyzed in terms of language, that is, as a composition of mediatic processes that continually modify the patterns of its experience. cellphones and online tools guide human nodes (a term i occasionally will rather use instead of users) to their destination, while indicate their movement through streets and places of interests, connecting millions of people in a narrative network, a virtual culture of the exchange of opinions (fact that allows certain authors to identify in contemporary networks a revival of certain aspects of oral cultures). cameras everywhere, either picturing a stage for someone’s life particular episode, either serving as control mechanisms. the sound of cars, planes, helicopters, undiscriminated publicity. radio-frequency communications. different but inter-related layers of information that can be thought as a platform to analyze, interpret and represent urban scapes and their complex vectors.

With a fast-changing mobile, network and simulation technology scenario, it’s always interesting to bring such discussion forward, not only to understand such a schizophrenic rate of ‘innovations’, but also to try to identify their impact in different cultural contexts, as well as to consider the consequences of an increasing obsolete material culture.

This AVLab tries to bring into this discussion a few distinct but somehow intertextual perspectives of a few artists and investigators.

The project Bineural-Monokultur (Christina Ruf and Ariel Dávila) will share their experience with their audio tours, a work that proposes an ‘actorless’ theatre, the city as stage for narrative sound interfaces.

The educators and researchers of the information science, Yamila Ferreyra and Valerya Sbuelz, propose a discussion around the possible cartographies of bodies, synergies and contrasts in between different urban territorialities in córdoba’s context. Their workshop will be based on the creation of possible strategies to map such circumstances.

My participation in the discussion concerns projection as a technology and a technique to provide visual interfaces for détournements: the technical moving and realtime image applied into space that superposes layers of visual subjectivity over urban scapes. There will be a quick workshop to present to the participants the basic idea behind projection mapping (based on previous meetings), using the opensource tool vpt. the workshop happens on september 20th, from 10am to 12:30pm.

After the workshops, at 2:00pm, a quick lab will be proposed, in which participant artists and workshop attendants will engage into the development of a possible installation to take place at the cultural center and its surroundings, during the night that closes the event.

Please visit the website of the Centro Cultural España to check the schedule of the event and to apply for the workshops.

The event will be streamed live by the CCE.

hope to see you there!

realtime image processing with puredata

procesamiento de imágenes en tiempo real con puredata

from august 25th to 28th, i’ll be at la cúpula media lab, in córdoba, argentina, for one more workshop. this time we will be using puredata as a tool for generating realtime images, a technique that can be applied to many different transmedia experiments in drama, cinema, performance, dance, vjing and so on. the program of the workshop is described below:

day 1

> discussion of the platform: what is puredata and what can it do?

> pd and libraries installation (a walkthrough in mac os and linux);

> intro to the patch metaphor / non-linear programming;

> intro to GEM/openGL;

> exercise 1: loading and displaying a video in GEM;

day 2

> exercise 2: puredata video mixer;

> exercise 3: realtime image filters;

days 3 and 4

> exercise 4: openCV – computer vision and puredata – face and other visual pattern identification;

> exercise 5: how to use arduino and puredata to modify images;

15 people limitation. you can apply yourself at the la cúpula’s website.

to leave you with an example of possibilities we will be discussing during the workshop, below there’s a video of a play i worked on with ricardo palmieri, gabriel camelo and the group les commediens tropicales. the multimedia scenery was made by using projection mapping techniques, with a combination of puredata and vpt (programmed by palm). hope to see you in córdoba!

presentation of process: demolición/ construcción residence

presentación del proyecto loci - demolición/construcción

what does it mean to historicise today? how do contemporary information storage and transmission mechanisms change the way the human memory functions? these are some of the questions that the project loci aims to address.

the name comes of the plural substantive of the latin term locus, which relates to a variety of concepts such as place, situation, state, etc.). the project was presented last saturday, july 16th, in la perla memorial, as part of my participation in the demolición/construcción residence. still on its early development stage, the web application was presented as a prototype, in an effort to discuss the development process with the other participant artists.

basically, my approach to the subject of the residence does not consider what can be thought as its most iconic aspects, as i agree with the idea of giorgio agamben about this clear incapacity we have while trying to understand these demonstrations of the inhuman, which can be identified in many historical circumstances of changes in the configuration of power, as in the argentinian dictatorship period, which lasted practically for almost 20 years, between the 1960’s and the 1980’s. having that incapacity in mind, i decided to privilege more broad matters that rely on the intersections between memory, art and politics. this conception gradually took form as i was reading agamben’s remnants of auschwitz and jose luis brea’s culture_RAM. based on the idea of testimony as a “relation between the sayable and unsayable” and of archive as “a system of relations between the said and unsaid” (AGAMBEN, 199: p. 45), i decided to discuss a broad concept of memory dimensions in contemporaneity, by proposing a meta-medium which makes references to certain human and computer models of archiving and retrieving information. as luis brea reminds us, after electronic and digital media, human memory continually tries to adapt itself to the reality imposed by the infoscape, an on-going mutation from a mechanism of retrieval to a channel for judgment of recent and simultaneous experiences. in this sense, the moralizing aspect of memory – the iconization of the past – has decayed in favor of more urgent needs: the preterization of the future and the networked understanding of an instantaneous, complex and continuous morphing information pattern. thus, luis brea relates the a ‘obsolete’ form of history to the computer ROM (Read Only Memory), and discourses about a change to what can be metaphorized as the computer RAM (Random Access Memory), stating that the notion of historical truth as a product of its materiality – to say, by archivable forms of culture – or of its provability (the testimonial of specific groups) is giving place to a systematic network of inter-projective processes, in which marginalized perspectives of traditional history emerge and interact with each other, proposing multi-discursive alternatives to what has been accepted as status quo. thus, the “truth” doesn’t matter that much: as long as the information is capable of crossing networks and has affective power, it has its value, no matter the nature of its discourse.


based on these assumptions, loci proposes a deterritorialization of objectified forms of history: archived information of different sorts of digitalized media formats (radio, television, newspapers, books, and so forth) are processed by a software that operates in three levels. one is mathematical, a continuous flux of data textures which are instantaneous results of algorithm calculus, juxtaposing and superposing different layers and types of media; other is linguistic, which relates the metadata which is associated with all information present in a databank, reconfiguring the network of relations at the textual level, operation  that interferes directly in what is “remembered” and emerges as interface;  which by its turn characterizes the third level, the perceptual: the fragmented images, texts and sounds that compose a continuous meta-form.

the databank for this 1.0 version of loci is composed of information that ran in mass media of 1970’s and 1980’s argentina. most part of this material was obtained during research in the archivo provincial de la memoria de córdoba, the cispren and the archivo del servicio de radio y televisión de la universidad nacional de córdoba. also, some friends helped with indications of popular culture references of that period. some youtube helped too :)

this databank is not meant to be permanent nor unique. loci is being developed not to be the information it handles, but the very process of in formation as a systematic metaphor of contemporary memory processes. this means that, in future versions, you will be able to load your own databank to loci, and integrate it with other databanks available in the web.

mapa mental loci

in other words, loci is proposed as a proto-memory, an evolving system that tries to ‘remember’ facts – rescue memorized information –  and, by doing so, it generates fictions and counter-facts (or hyper-facts, as i would like to frame) by saving the modified “memories” as new facts in the databank. also, it is intended that loci will look for related information present in the web, by using APIs of engines such as flickr or twitter, extending the historical and meaning spectrum to other limits, to the limit of what wittgenstein defined as language barrier.

the application will be available in the web as soon as i finish the 1.0 version, which shall happen in the following weeks. the release will be announced in this blog. the core development is being done in processing, and the source code of the application will be available on its release.

more details on the development of the application will be revealed soon. i also intend to publish here a text that conceptually supports the project (as i initially announced a couple of weeks back).

the presentation of the project was very pleasing precisely because of the feedback i obtained from the other artists and thinkers, and i would like to say a big thank you to all for that. a special thanks goes to lina lopes (who i would also like to thank for taking most of the presentation pictures), gabriela halac, graciela de oliveira and eugenia almeida for their interest and contribution to the subjects of the project. and thanks to ángel poyónfhernando poyón and edgar calel for the great exchange of ideas during or time in fundación pluja, which i would like to thank for the hospitality.

i would also like to thank the la perla memorial, the cispren, the archivo provincial de la memoria de córdoba and the universidad nacional de córdoba for their support to the research.

and of course, a big thank you to graciela de oliveira and soledad sanchez for the incredible effort in organizing the phronesis criolla residence.

here are a few images and a video from the presentation day, in la perla. stay tuned for more information about the loci project.
